The Flotronic® WALL-HUNG shower system provides users either no-touch, unique patented 9V lithium battery-operated electronic activation as standard equipment, or an optional manual air-controlled pushbuttonmetering (adjustable from 5 to 60 seconds) valve. As an alternate, the Flotronic can be activated by a piezo electronic touch button. The electronic system is completely self-adjusting and eliminates the need for time consuming and inaccurate setup procedures.
